We divide 124230 by 18
The aim is to understand the frequency of 18 in 124230.

Going ahead to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 18

Advancing to step 2:
18 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 18

Let's proceed to step 3:
When dividing 124 by 18, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 108 from 124 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 18

Advancing to step 4:
If we divide 162 by 18, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we subtract 162 from 162, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 18

Step 5:
When dividing 3 by 18, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 690.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 18

Step 6:
When dividing 30 by 18, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 6901.0
If we take 18 away from 30, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 18, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 6901.6
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6901.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 6901.66 with a balance of 0.012.
